Paul Walker Tells Lopez That The Rock and Vin Diesel 'Lubed' Each Other Up (VIDEO)

Paul Walker may have busted open a trade secret he should have left buried about the set of 'Fast Five' during his appearance on 'Lopez Tonight' (Weeknights, 12AM ET on TBS). He certainly seemed pretty worried about the bizarre details he laid out there for us all to imagine.

According to Walker, there were scenes in the film where the actors might have wanted to look sweaty, but it wasn't hot enough to have it occur naturally.

"You gotta use some body lube," he said. "You got Dwayne [Johnson] and Vin [Diesel] doing a lot of lubing each other up."

Walker thought this was the set-up to his funny story about the pair spilling lube on the ground, creating hazards when they were shooting scenes like running across rooftops. But Lopez only heard that The Rock and Vin Diesel were rubbing each other down with lube.

"Maybe I shouldn't have gone there," Walker lamented. "Dwayne, Vin, I swear to God I'm sorry. I was just trying to be funny."

Later, to dig Walker's hole a little deeper, George Lopez brought out a modified 'Wet Floor' sign for use when those two were doing scenes together. The new sign warned, "Caution: Slippery Wet Men."
